subtract 20 from both sides:
3x+20-20=80-20

Answer 2

3x + 0 = 60
3x = 60

Answer 5

Distribute (or multiply) 2 to 3x and -20, eliminating your parentheses.
thus you would have...
2x + 6x - 40 = 80.

Then join your like terms together to make your equation shorter.
2x + 6x
and you end up with...
8x - 40 = 80
then start to isolate your variable!
add 40 to -40 and 80.

8x = 120

now divide 8 to both sides, isolating x!
x = 15
